n'zarnnf Original No. 1,660,802, dated February 2s,'1e2s,seri 1 Nix/125,471, filed July-28, 1926. Application for reissue filed July 23, 1928. Serial No. 294,860.

My invention relates to driers and the principal object of my invention is to provide a new and improved device of this type. In the drawings accompanying this specification and forming a part of this application I have shown, for purposes of illustration, one form which my invention may assume. In these drawings: I V I t Figure 1 is a 'general view of this illustrative embodiment of my invention,

Figure 2 is a horizontal section taken on the line 22 of Figured; and enlarged, while Figure 3 is a diagrammatic representation of the electrical system-.

The embodiment of my invention herein shown comprisesa ran 11 secured to one end of the'shaft 12 of a inotor 13 which carries at its forward end a heater 14 and a lamp socket 15 both supported upon an insulating base 16. carried by two armsl'? extending outwardly from lugs '18 formed on the housing 19 of the motor 13, the. entire fan-motorheatcr-socket unlit being supported from a supporting rin'grQO by means of radial ribs 21 cxtending between the motor housing 19 and the supporting ring 20. The entire unit is enclosed by a pair of easing sections 22 and 23 which overlie reduced shoulders 24 and 25 tormedrespectively onthe rear and forward sides of the supportingring 20, and are secured tothe ring in any suitable manner, as

by set screws 26 extending through the casing sections 22 and 23 into the reduced shoulders 2-.t and 'respectively, and the supporting ring 20,'and the entire unit carried thereby, including the casing sections 22 and 23, are supported by means of a bracket 27 integral with the supporting ring 20 and itself providcd with a circular projection 28 adapted to be held by means of a bolt'29 in cooperating pivotal relation to a similar circular ,projection 30 carried by a block 31. provided with a pin arranged to be rotatably received by any suitable socket, such as the recess 33 extending downwardly into the top of a shank 34 itself arranged to be received with in the bore of a stem 35 which is provided with a setscrew 36-to lock the shank 34in adjusted position and is itself supported from base 37 having a central annular portionv 38 provided with a recess 39 for the reception of the lower end of the stem 35, having a set screw 40 to hold the stem 35 in position in the base 37 and provided with three legs 41 each provided with a lamp 46,'and with a reflector 47 directing the light and heat from the lamp 46th'rough the outlet opening 45, and the various parts of thedrier, including the fan '11, and the casing sections 22 and 23, and

-the ribs 21, and the niotor casing 13, and the heater 14, and the reflector 17 and-the opening 45, are all so formed and proportioned and positioned that the air drawn in by the fan 11 through the opening 43 in the casing section 22 is given a rotating or swirling motion which is permitted to persist throughout the entire length of the casing 23 so that v the air emerges through the opening 45 still swirling and only at the periphery of the opening 45, andthere isproduced a secondary air current flowing into the opening 45 throughthe center of the swirl drawn in by the suction produced by the swirl itself;

Operating power for the entireunit is provided through a pair ofline wires'48 and 49 connected to a main switch 5 0 provided with a first terminal 51 receiving the line wire 48, and with a second terminal 52receiv-ing the line wire 49, connected by means of a conductor 59 to a switch 60 in turn connected by a conductor 61 t0 oneterminal of the lamp 1 5,

to a switch arm. '54 having three operating positions in the first of which it engages a blank contact 55, in the second of which it engages a terminal 62 connected by meansduo-tor 57 to one terminalof the heater 14,' the other terminal of the heater 14 and the and also connected by means ofa conductor 53 other terminal of the lamp 15 being connected by branch conductors 68 and 69 to a sub-conductor 70, the other terminal of the motor 13 being connected by means of a conductor 71 to a resistance 7 2 having its second terminal connected to a sub-conductor 73, and the two sub-conductors 7 t) and 73 being'connected by means of a conductor '74 to the terminal 51 of the switch 50. v 7

From the above description it will be understood by those skilled in the art that by placing the switch 50 in the second pos tion I energize the motor 13 and fan 11 without energization of the heater 14, and that with the switch 50 in the third position I energize both the motor 13 and fan 11, and also the heater 14, and that the lamp 15 may be energized at any time independently of the energization of either the motor 13 or the heater 14, and depending only on the position of the switch 60.

. Under these circumstances those familiar with driers of this type, and with the use thereof, for drying'hair, will appreciate that I can secure the operation of any of the three devices or any combination of the three devices, likely to be desired for that purpose, and also that by virtue of the air currents set up by the embodiment of my invention herein shown and described I can produce an air current which flows from the drier in a gentle expanding stream flowing outwardly about the head and then returning through the hair itself to supply'the air drawn in through the center of the swirl.

Under these circumstances those skilled in theart will appreciate that I have produced a new and improved drier.

At the same time those skilled in the art will realize that the particular embodiment of my invention herein shown and described may be variously changed and modified without departing from the spirit of my invention or sacrificing the advantages thereof-and it will therefore be understood that the disclosure herein is illustrative only and that my invention is not limited thereto.
